Sera Filter Wool 3.5oz

sera filter wool is designed for effective mechanical prefiltration, featuring durable fibers that trap fine dirt particles over extended periods without clumping or breaking down. This filter wool can be cleaned and reused multiple times, making it a versatile choice for all types of filters.

For optimal biological filtration, we suggest pairing it with sera siporax Professional, which offers a unique open-pored, three-dimensional structure for consistent pollutant removal. Before initial use, rinse sera filter media in warm water to prepare it for your system.

Helpful Hint:
Combine sera filter wool with sera phosvec･clear to simplify the removal of accumulated substances from your filter.
